[UC] Picking up a Discarded Onee-Chan… (Mama Hame!) [Tabunne Scans]

An unemployed youth named Shimoda Yui is taken in by his voluptuous older sister, whose massive, glistening breasts and seductive demeanor promise a desperate escape from loneliness. She eagerly offers him a place to stay, teasing him with provocative gestures and a promise of a 'proper breakfast' that quickly turns into a heated encounter, culminating in a fierce ffm threesome where her enormous breasts and tight, wet pussy dominate the scene. The story blends the tension of his virginity and her maternal authority with explicit, full‑color intimacy, delivering a tantalizing mix of incest, paizuri, blowjob, and shotacon fantasies.
